o Cov tsev muag tshuaj
o Dyes thiab pigments
o agochemicals
Muab cov pab pawg tsim qauv (-ch₂oh) thiab sulfonate moiety, muaj txiaj ntsig hauv ntau yam kev ua kom haum thiab hloov pauv
2. Stabilizer rau Aldehydes
● Siv los ua kom ruaj khov dawb formaldehyde hauv cov kev daws teeb meem aqueous
● Ua raws li cov tuam txhab tsis tsim nyog lossis cov tsis tau, tso formaldehyde nyob rau hauv cov xwm txheej
● Hauv:
o Rogram tsim khoom (piv txwv, urea-formaldehyde, phenol-formatherehyde resins)
o Textile ua (xws li, formaldehyde-tso tawm cov neeg sawv cev-resistant)
3. Kos duab thiab Kev Ntsuas Tshuaj
● Siv cov yees duab tsim qauv raws li cov tshuaj tsis huv thiab stabilizer
● Pab kom muaj kuab lom pH thiab tshuaj lom neeg muaj kev ruaj ntseg ntawm cov da dej
4. Textile thiab Tawv Kev Lag Luam
● Ua haujlwm raws li cov neeg ua haujlwm tsis raug nyob rau hauv Textile cov neeg sawv cev (piv txwv li, tiv thaiv wrinkle lossis ruaj-xovxwm tag nrho)
Qee zaus siv hauv tawv tanning rau nws me me txo thiab aldehyde-muab cov khoom ntiag tug
5. Dej Kho thiab Kev Tu
● Cov haujlwm ua tus ntxhiab lossis txo tus neeg sawv cev rau khi thiab neutralize aldehydes thiab lwm yam oxidants
● Siv hauv cov boiler tu cov neeg sawv ntxov, tshuaj tua kab mob, thiab kev txiav txim siab
6. Kws paus tshuaj
● Hauv cov xwm txheej tshwj xeeb, siv los ua cov tshuaj tiv thaiv hauv cov tshuaj sththesis lossis tsim kev zam txim, tshwj xeeb rau tswj aldehyde tso tawm los yog buffering

1. Tswjhwm Formaldehyde tso tawm
● Ua raws li kev nyab xeeb rau txoj kev pub dawb rau cov lus teb pub ib puag ncig (piv txwv li, pH, PH, PH, PH, PHAS)
● Txo cov kev pheej hmoo cuam tshuam nrog kev siv cov nyom lossis cov formatous formaldehyde
2. Cov kua dej solubility thiab tuav kev nyab xeeb
● Tag nrho cov soluble hauv dej, ua rau muaj kev koom ua ke yooj yim rau hauv cov tshuab aque
● Ntau ruaj khov thiab tsis txhob hloov me me dua li formaldehyde, ua kom muaj kev nyab xeeb dua rau khw thiab lis
3. Ntau Yam Ntau
● Cov pab pawg sulfonate tau txhim kho solubility thiab ua rau nws haum rau synthesis thiab tsim kev ua haujlwm thoob plaws ntau cov tshuaj muaj kev lag luam
4. Nqi siv nyiaj nruab nrab
● Npaj txhij muaj thiab kev xaiv tau, kev xaiv zoo rau buly daim ntawv thov nyob rau hauv resin ntau lawm, textiles, thiab tshuaj lom neeg raug

Sodium formaldehyde bisulfite 丨 cas 870-72-4}} soluble reagent rau nws muaj peev xwm ua kom ruaj khov thiab tso formaldehyde hauv kev tswj hwm. Nws ua haujlwm ua ib qho tseem ceeb nyob rau hauv textile xaus, muab tshuaj kho, duab tshuaj, thiab synthes organic. Nws qhov tsis muaj hluav taws xob qis, nthuav tawm cov khoom siv ua rau nws muaj kev sib xyaw ua ke thoob plaws cov tshuaj, textile, thiab kev ntsuas kev nyab xeeb nrog kev nyab xeeb thiab nqi zog.
